The method is universal. The materials are local. Any coastal nation can start a nursery with rocks, seawater, and basic construction skills. Here are the sea basins where the opportunity is greatest.
We're beginning with two pilot sites — the Mediterranean and the Baltic — because we have the local knowledge, partnerships, and presence to start there first. But this isn't a sequence. The protocol is open source. The materials are available everywhere. A fishing community in the Philippines or a marine research station in Kenya could begin adapting this approach with minimal resources right now.
Each region below has its own ecological profile, target species, available substrate, existing restoration work, and funding pathways. Click through to explore the full case for each basin.
Heavily degraded seabed warming 20% faster than the global average. Home to the basin's only reef-building coral and rich gorgonian communities ready to colonise new substrate. Abundant limestone, year-round nursery conditions, EU funding.
Semi-enclosed sea in ecological crisis — dead zones, collapsing fisheries, declining mussel beds. A completely different ecosystem from the Mediterranean, proving the method is universal from day one.
The highest marine biodiversity on Earth. 75% of all known coral species, 120 million people dependent on reef ecosystems. Vast coastline, abundant volcanic rock, established aquaculture traditions. Greatest total impact potential on the planet.
80% coral cover lost in 50 years. Tourism economies directly dependent on reef health. Small Island Developing States facing existential reef loss. Strong existing nursery programmes ready to integrate with industrial-scale deployment.
East Africa's reefs lost up to 80% of coral in the 1998 El Niño. Communities whose food security depends entirely on reef ecosystems. The method's low cost and low-tech requirements make it uniquely suitable here.
Native oyster populations reduced by over 95%. Centuries of trawling left featureless seabed. Growing political momentum for marine restoration. Offshore wind farms creating no-trawl zones with ideal conditions for habitat creation.
For Pacific Island nations, reef loss is existential — food security, coastal protection, building materials, cultural identity. Deep traditional knowledge of reef management. The most urgent need for affordable, scalable restoration anywhere on Earth.
We don't only plant trees where forests used to be. We can build reefs wherever the ocean is willing — and the ocean is always willing.
